如何获得SAS的中值？

如何获得SAS的中值

我写了一个剧本，但它没有让我明白

这是我的剧本：

   FILENAME book1 URL "http://www.math.tau.ac.il/~liadshek/Books.txt";
   DATA book;   
   INFILE book1 firstobs=2;
   INPUT year numberBooks words copies annual author$;
   RUN;

   PROC MEANS median;
   VAR year numberBooks words copies annual;
   OUTPUT out = MeanForData;
   RUN;

---

这段代码在Base SAS中运行良好

您只需打开输出窗口即可查看结果（它们通过输出传递系统发送到那里）

---

中位数需要在输出上

   FILENAME book1 URL "http://www.math.tau.ac.il/~liadshek/Books.txt";
   DATA book;   
   INFILE book1 firstobs=2;
   INPUT year numberBooks words copies annual author$;
   RUN;

   PROC MEANS;
   VAR year numberBooks words copies annual;
   OUTPUT out = MeanForData median= /autoname;
   RUN;
